I Just picked it up 4 hrs ago and It does have some lag with the kinect adventure.
However I can tell you I have had a lot of fun with it so far.
My girl expecially, she has been playing for 3hrs straight and Loves it. She has a wii and I asked what is better. She without hesitation said, "kinect for sure".
I see the potential in this though. I think with hardcore games they just may need a glove or some sort of extra attachment to go with the game. Or a update to understand hand gestures. Maybe the game software can update it the way they want it. I diffently got what I wanted out of it so far and that is social fun with friends, my girl, family.
Only played with my girl but I can tell this will lead to some good drinking games.
The lag could be the software if not I'm sure they will update the tech and tighten it up. Wii had the same problem.
All and ALL I'm very happy I got it.
